Second kills are always far easier than the first, because you don't have to learn the fight =P. We oneshot things like Council second kill etc - my disbelief was that they could spend 180 wipes LEARNING qon. That seems really, really extreme (especially concidering how long 180 wipes takes, as I've just gone through that with lei shen).

The reason you die when standing in the yellow beam second time on Durumu is because you shouldn't :P. You get a stacking damage-taken debuff from the beams that lasts the entire encounter, so you're supposed to have people rotate which beam they stand in, so the buff never keeps stacking up. So if you go yellow first, go blue second etc :P.
Offtopic, but hey, might help you guys out a bit.

Oh, I've just done as I've been told x] Now I got an answere atleast, and we should be able to kill him easier :P Thanks .)

The boss I've wiped the most to? Stone Guard, both difficulties. At the start, we had a bad tank for a week. We moved the tank to dps, and got a new tank, and then one shot Stone Guard after about 123 wipes.

Tortos comes to a close second, with 112 wipes.

Anyone ever notice how the sun seems to shine silverish now? Didn't it used to shine goldish? PM me if you've noticed this.

Pre-nerf Horridon was a pain, despite even having four heroics down before ToT. (But between you and me, I think it was because all of our melee at the time never interrupted. Though we didn't have a lot of multi/cleave either...noticing a pattern here)

Finally, Durumu, still wipe on him consistently. Instead of the same four people managing life drain, now there is 5! (Can't wait till heroic mode!)

You have to love how 123 wipes isn't even enough for some people to learn to play

It was Heroic Vizier in Heart of Fear for my guild. Fight was so rough the way we were doing it. Wiped at 200K health the very last night of 5.1. The boss got caught on the stairs and cast his Force and Verve all over the room because he was glitching. Wiped. Guild Vent went berserk. Glad that's over.
